Lazy Redstone
by LitQA
Lazy Redstone is a Forge and NeoForge mod whose blocks condense classic redstone farms and duplicators into single placeable blocks.
What it does
Many common automation builds, such as string duplicators, carpet duplicators, TNT duplicators, iron farms, stone generators and TNT tree farms, normally need dozens of blocks, multiple pistons and long redstone lines. The mod replaces each of these designs with one block that performs the same job. Most blocks start working as soon as they are placed, and some open a GUI where input materials set their options. Container-like blocks such as the mob trapcage and the villager concentration camp show the mob type and count, and mobs inside them are held directly.
The string duplicator works like the vanilla version, facing north or south and producing string immediately, and it also functions on the later Forge and NeoForge versions where the vanilla design stopped working. The TNT duplicator lets the player set an explosion delay in game ticks through its GUI. The mod is published for Forge and NeoForge, with files for 1.20.1 and 1.21.1. It runs on client and server, so the server and every player need it, and it is not open source, being released under All rights reserved. It works with the integrated farm frame.
Key features
Single-block farms
Iron farms, stone generators and TNT stone factories are each reduced to one placeable block.
Duplicators
String, carpet and TNT duplicators copy items in one block, and a right-click duplicates an item once.
Configurable TNT delay
The TNT duplicator's explosion delay can be set in game ticks through a GUI.
Mob containment display
Trapcage and villager camp blocks show the mob type and count while holding mobs inside.

Use cases
Survival automation
Players who want automated resources without wiring clocks and piston timings can place a block instead.
Who it’s for: Survival players who want farms and duplicators without building redstone contraptions, and server owners who want compact automation on a shared world.
How it compares
Item Duplicator is a Forge-only, client and server mod for 1.16.5 – 1.20.1 under All rights reserved, so it does not cover 1.21.1. Copy-Item is open source under the MIT License, published for NeoForge on 1.21.1 only and also needs both sides. TNT-Bombing covers Forge and NeoForge across 1.20.1 – 1.21.10 under a Creative Commons Attribution No Derivatives 4.0 license and is not open source.
